Importing and Exporting Expressions

Importing and Exporting Expressions

Top 

You can copy expressions from Geometry Expressions and paste them into an algebra application such as Maple™ or Mathematica®, and you can also copy expressions from such applications and paste them into Geometry Expressions.

To enable this, Geometry Expressions uses the standard MathML™ interchange format. MathML Mathematical Markup Language is an extension of the widely adopted XML protocol, designed for mathematics applications.

The official MathML web page and specification is at:

www.w3.org/Math/

MathML comes in two varieties:

  • Presentation MathML
  • Content MathML

When copying from a companion application into Geometry Expressions, use Content MathML, which is the variety that Geometry Expressions accepts.

As a convenience, Geometry Expressions places expressions you copy on the clipboard as both Presentation MathML and Content MathML. Many applications can accept this dual input and choose the variety they require.

Some applications, however, might not be able to accept dual input. If you are having difficulty with an expression copied from Geometry Expressions:

  1. Consult the users guide or help system for the target application to determine which variety of MathML it accepts.
  2. Use Edit > Copy As… to invoke a dialog enabling you to choose between the two varieties. Only the one you choose is placed on the clipboard.
